> Issue Type: Bug
> Components: qjm, test

> Reporter: Todd Lipcon

> TestQuorumJournalManager can occasionally fail if two consecutive test cases
> pick the same port number for the JournalNodes. In this case, sometimes an
> IPC client can be cached from a previous test case, and then fail when it
> tries to make an IPC over that cached connection to the now-broken
> connection. We need to more carefully call close() on all the QJMs to prevent
> this.
